American social psychologist Stanley Milgram proposed a theory called six-dimensional space. The theory points out that there will be no more than six people between you and any stranger. In other words, you can get to know any stranger through up to five intermediaries. Through this theory, I learned that the relationship between people takes on an intricate network-like form. That is to say, each of us has a radial network of relationships, and the network will continue to expand through the people we know.
So, I just know them.
